what's your engine again? Cubic inches, compression ratio?
Ford 302 9:1 not stock by any means either.
Well crap-i was hoping this was on your 454 (thought thats what you were running). I've had this VR4 for a few years and it's probably not worth rebuilding/using since i've been told it just wont push the air needed to do much good on a built 415 inch small block dodge. I only want 8-10 psi or so, but i guess the CFM just isn't there. Might need to look elsewhere. Glad to see it's pushing you in the seat hard.-rick
What size pulleys do you have on it if you go with smaller supercharger pulley you will get 8-10 lbs the vr4 pushes as much cfm as a novi 2000. What year did you buy the vr-4? Did you buy it when the granetellis still owned paxton?
Never installed it- needs a rebuild. Unknown age- i got it about 5 years ago from someone that had it on his shelf for maybe 5 years. He purchased it from Paxton as a rebuild that a Renegade racer sent in (i think when Paxton stopped paying contigency money for racers that wouldn't switch to the newly released Novi). I just posted a big long speal about how i'm not sure if this is worth my time/money to rebuild and install-rick
Send a picture to my email I've heard the vr4 impeller was different when the granatellis owned it.
Ill buy it if you want to sell it?
